“…Polymer matrix usually consists of epoxy, vinyl-ester or polyester thermoset plastic [3] because of its excellent properties and cost. Glass, cellulose, aramid, silicon-carbide and carbon fibers are commonly used fibers in FRP [4]. Fibers are mainly added to polymer matrix to increase the properties of strength, modulus and impact resistance.…”

Glass fiber reinforced polymers (GFRP) is a new material with many advanced features in terms of strength, light weight, anti-corrosion ability on salty environment, which may replace steel. In this work, we present the technology of manufacturing of GFRP in bar form: pultrusion technology. The production line at the factory is imported from abroad. The objective of the research is to step by step mastering the technology and fully master the production line system of GFRP in bar form in Vietnam. We have fabricated successfully a product of high applicability, which has great potential for development (GFRP in bar form with large diameter, 20 mm). Pultrusion is one of technologies to fabricate the polymer composites used in many industries such as in aerospace, automotive and construction ones industries. The high performance pultruded products that are produced by this technique offer high fiber content of at least 70%. In order to produce high quality pultruded profiles, there are variables such as fiber impregnation, resin viscosity, pulling speed and curing temperature that have to be considered and these requests are discussed in this study. The aim of the present work is evaluating elastic properties like Young's modulus and Poisson's ratio from analytical methods such as Rule of mixture, Halpin-Tsai, Nielsen, Chamis and Hashin elastic models and compared with experiment results. The result shows a big difference. The mechanical characteristics of the GFRP D20 bar depend not only on the composition of components (fiber and epoxy) but also on the manufacturing technology. We propose research further direction: optimize the technological element in manufacturing GFRP bar with large diameter.

“…GFs with favorable mechanical properties as well as high length‐to‐diameter ratio show substantial reinforcements in epoxy composites . Very low incorporation of GFs in these composites has often caused an exceptional enhancement in mechanical properties while the polymer attributes of low density and simplicity in processing have been maintained . However, full development of GFs reinforcement has not been entirely successful in polymer composites due to the restrictions of relative low compatibility and weak interaction between GFs and polymer matrix .…”

Glass fibers (GFs) and hyperbranched polymers with amino terminal groups (HBPA) were introduced into epoxy/ polyamide system to fabricate high-performance composites. The impact resistance and mechanical characterization of epoxy/HBPA/GFs composites was performed to investigate the effect of GFs in the composites. The composites revealed noticeable improvement in tensile strength, elongation at break, flexural strength as well as impact resistance in comparison with the unmodified and HBPA modified epoxy/polyamide thermosets. FESEM morphologies showed that the toughening mechanisms could be attributed to the yielding deformation, phase separation and micro-crack toughening mechanisms. POLYM. COMPOS., 00:000-000,

The aim of present work is focused on the evaluation of elastic and thermal properties of unidirectional fiber-reinforced polymer composites with different volume fractions of fiber up to 0.7 using micromechanical approach. Two ways for calculating the material properties, that is, analytical and numerical approaches, were presented. In numerical approach, finite element analysis was used to evaluate the elastic modulus and thermal conductivity of composite from the constituent material properties. The finite element model based on three-dimensional micromechanical representative volume element (RVE) with a square and hexagonal packing geometry was implemented by using finite element code ANSYS. Circular cross section of fiber and square cross section of fiber were considered to develop RVE. The periodic boundary conditions are applied to the RVE to calculate elastic modulus of composite. The steady state heat transfer simulations were performed in thermal analysis to calculate thermal conductivity of composite. In analytical approach, the elastic modulus is calculated by rule of mixture, Halpin-Tsai model, and periodic microstructure. Thermal conductivity is calculated analytically by using rule of mixture, the Chawla model, and the Hashin model. The material properties obtained using finite element techniques were compared with different analytical methods and good agreement was achieved. The results are affected by a number of parameters such as volume fraction of the fibers, geometry of fiber, and RVE.
